    Hello Abu,

    Display can’t be turned off unless power is disconneced. You can add switch  for input port.

    If converter get power through output port, the most serious problem is backfeeding, that will damage converter.

    For charging battery, please connect diode to output port to stop backfeed current.

    Best regards.

    in reply to: Buck Converter Step Down Voltage Regulator Charging Indicator #87677

    Hello,

    That is not warning sign, charging led is charging status indicator. When actual current is below 10% of preset current, that means battery is almost full or it is not charging.

    Best regards.
